ICP Furnace Control Board for WPG3484130RKC1 — Integrated Ignition Control | Ships Today

Overview

This OEM integrated furnace control board (circuit board P/N 1178358, ignition control module P/N 1177661) is the brain of the ICP WPG3484130RKC1 packaged gas/electric unit. It manages the ignition sequence, monitors flame, sequences the inducer and blower, and protects the system through its safety interlocks on the 24V control circuit. When this board fails, the furnace section will not light, will short-cycle, or will lock out — leaving you with no heat. Common failure signs include a unit that hums but never ignites, error/flash codes on the diagnostic LED, or intermittent operation in cold weather.
